IMPROVEMENT IN BED-FRAMES AND A'ITACHMENTS.

Specification forming part of Letters Patent No. 129,191, dated July 16, 1872.

SPECIFICATION,

I, JOHN M. FARNHAM, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Bed-Frames and Attachments therefor, of which the following is a specication, reference being had to the accompanyingdrawing, in which- Figure l is aview, in mechanical perspective, of the upper left-hand corner of a bed-frame bearing some of my improvements. Fig. 2 is a view, in crosssection, of the head rail and canvas through the dotted line a: in Fig. 1, showing how the Vcanvas vis fastened to the rail. Fig. 3is a view, in mechanicalperspective, of the lower right-hand corner of a bed-frame bearin g some of my improvements. Fig. 4 is an elevation view of the inside of the side rail and corner attachment shown in Fig. 3.

My improvements consist of new and useful corner pieces for attaching the end and side rails of a bed-frame together; in a new method and means for attaching the canvas or its equivalent to the head rail; and in a new construction for the foot rail.

First, with reference to the parts shown in Fig. l: The letter a indicates a side rail, and b a head rail. On the end of the side rail lits a head corner piece, made of metal, consisting of a socket, like a cap or boss, which fits upon the end of the rail embracing the sides of the rail at c with a short flat strengthening-arm, c1, on the under side of the rail, and a similar longer arm, c2, on the top of the rail, and bearing a socket or rest, c3, for the end rail. From the inner lsidel of this socket extends an arm, c4, in the upper edge of which is a notch, c5, into which falls the pin b1`,\vhich projects from the head rail and thereby prevents the head rail from turning When a strain is put upon the canvas. There is a screw-hole, c6, in the arm c, whereby the arm may be screwed to head rail, thus serving to hold the side rails together. On the arm c2 is a clamp or saddle, ca, to keep this arm from motion sidewise. In constructing this head corner piece it is not absolutely essential that it should conform in all particulars to the description just given. It is essential that it should be a boss or cap for the end of the side rail, that it should have a socket or rest for the end of the head rail,

and that it should have an arm, c2, or some equivalent therefor, Yto prevent .the head rail being canted or pulled forward by the strain l of the canvas. It is an important adjunct to have the arm c4 with its notch and pin and its screw-hole, the notch and pin to prevent the turning of the head rail when it is round or of any` other shape liableto turn, and the screw-hole to serve the purpose already 'indicated. As just implied, it is not essential that the head railbe round, for it may be of any other shape; but, in such case, the shape of the socket c3 must conform thereto. with reference to the method of attaching the canvas, or its equivalent, to the head rail, or other rail, if desired, shown in Figs. 1 and 2: There is a round hole, b2, bored through the length of the head rail, and then a small slit is sawed into it from the exterior of the rail. The canvas d is then folded double, leaving the end d1 underneath, and the fold is pushed into the slit. A round rod, e, is now introduced from the end of the rail between the two thicknesses of cloth, and the hardest pull upon the canvas toward the foot of the bed win only make the @10th hola the tighten/i Third7 with reference to the foot corner piece and the foot rail shown in Figs. 3 and 4: The letter a in this case also indicates theiside rail, and f indicates the foot rail. The foot corner piece is in all respects the same as the head corner piece except that it bears a different kind of socket for the end of the foot rail. The top of the foot rail is beveled from rear to front, so that the canvas which is stretched over it shall touch nowhere but at the rear edge. To effect this bevel in practice, the 'K foot rail may be sloped from rear to front and and the socket c3 canted accordingly. The end of the foot rail, which fits into this socket, has a groove cut in it, fitting upon the projecting ridge c7 made for it on the inside of the socket.

It is desirable to have the foot of the bed-frame round-cornered, and at the same time to have the canvas or other fabric cover the foot rail from end to end. It is necessary that thecanvas should be a level surface from side to side; but it is evident that these three conditions cannot be fullled unless something is invent ed to keep the starting point of the canvas (from z to z) level. I effect this by raising a Secondf ridge on the rounded ends of the i'oot rail, which makes the outline of the rail from z to z' perfectly level. 0n this foot corner piece,

the same as upon the head corner piece, is the arm c4 with its screw-hole o6 for holding the side rails together. restingby one end upon a pin on the foot rail, and the other end upon a pin on the inside of the side rail, thus acting as a strengthener.

It will be readily seen that a bed-frame constructed in this Way can be taken apart and packed into a small compass for transportation, and can be readily put together again for use.

I claim as my invention-f- 1. The head corner piece, fitted to the side rails, with its arms and sockets, constructed as described, and for the purposes set forth.

The letter m indicates a brace 2. The rounded foot corner piece with its arms and sockets, constructed as described, and for the purposes set forth.

3. The tubular roller with its slot and rod for securing the canvas, as described.

4. The combination of the side rails, the head and foot pieces with the corner sockets and arms, ali constructed as described, and for the purposes set forth.

5. The foot rail having its ends rounded and ridged, as described, for the purposes set forth.
